I have a i4 with 4.0 and TU v4.00.80 isn't recognizing my device. I have a 3GS it recignized and I was able to back up my SHSH files but I really need to get the i4 backed up. Any ideas? I've tried rebooting the phone, TU, and the computer. I'm trying to run this on a Windows box as the TU I downloaded for my Mac won't launch at all.

here and from TU site. i figured when i uncheck "open safe downloads" or what ever it will download it as dmg. when i mount/open i copy the software to application or desktop. when i run it, it keeps bouncing and nothing happens... any ideas?

Okay so I'm using a new i4 and have no access to a Windows or Mac for the next couple of days. I'm on a Mint Linux system...Here's what I've done. I've saved my shsh blobs using TinyUmbrella. I went to advanced options and picked Cydia. What I'd like to know, is there any chance I can get a confirmation of sorts just to know if my blobs where really saved to Cydia? Or if possible, does anyone know where they would be saved locally on my computer so I can throw them onto a flash drive just to be safe...Thanks any help.
